Re: K7 & cpu disconnect

[Thomas Herrmann]

Hi Len,

one more data point wrt this topic.

I can enable STPGNT/CPU disconnect on my NForce2 system running WinXP while
using the tool from http://www.hasw.net/8rdavcore. And guess what, the system
runs stable for hours, not locking-up at all. Since this is exactly the same
hardware as well as BIOS configuration, it leads me to beleave the Linux
ACPI/IO_APIC implementation has an issue.

BTW, it seems the acpi-devel list archive on sourceforge.net hangs, no new
entries since 01/24/04.

Regards,    Thomas

Obviously I missed what led up to this message, but are you talking about
your box hanging under heavy io (badblocks, fsck, du etc)? I think most
nforce2 boards have this disconnect function in the bios. Anyway, my box
hangs under heavy io (abit nf7-s barton 2500+) under 2.4.23 with APIC in
the kernel, but not under 2.6.0-test11. In this kernel I have APIC
disabled. If you haven't done so, you kan check lkml archives for messages
by Ross Dickson, he brought this up there.

I think the 2.6.0-test11-mm tree has a patch cycled in with regards to
nforce2 (two actually) I can dig up the URL if you are interested.

Regards,

Arjen
